Perhaps you should try some spelling variations:
prestados » prestadoras, prestadores, prestadora
presentados » presentado, presentadas, presentaron, presentedos
presentation » presentan, presentetion
presentent » presenten, presente, presentan
presentar » presentan, presentarse, presente, presenter
presentacion » presentecion
presenta » presente

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((prestados OR presentados) OR ((presentation OR ((presentent OR presentacion) OR presentar)) OR presenta))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((prestados OR presentados) or ((presentation or ((presentent or presentacion) or presentar)) or presenta))~".
• Adding a wildcard symbol may retrieve word variants: ((prestados OR presentados) or ((presentation or ((presentent or presentacion) or presentar)) or presenta))*.
